Fascinating design. But I think I'd want mine painted. Even if it wasn't all faired out and glossy. But just primed and painted with a satin or semi-gloss.

If you paint it you have to keep painting it. Bare aluminum just needs a little "Aluma-Brite" to get the shine back. Fairing and coatings add weight and cost. I wonder how watertight those vents on the foredeck are and how well the gaskets on the foredeck hatches work. I'm sure those windows are "Classed for Ocean Service", but there is something about a having a storm plate that makes me fell better. I can feel it shaking and shuddering just looking at the slide show. Cool boats thought, I do like the logic behind these boats.

Sitting on an aluminum boat now, so I hear ya. But note I said without fairing. :-)

Interesting questions. But from what I've read about Dashew, I'd guess he has addressed those issues.

Looks like a fun trip . I'd think there must be a lot of force acting on those interesting stabilizers. Slick design boat.

Nice looking boat and great slideshow.

I agree with L Keith, I'd feel a lot better if those forward windows had some protection... if nothing else a breakwater on the foredeck.

Here's your answer on the windows. http://www.dashewoffshore.com/glazing_decision.asp

The stabilizers are just good old NAIADs.

Wow- 19mm/3/4" hardened safety glass. Looks like the bigger issue might then be the strength of the framees that hold that glass when subjected to the waves in the video or larger as the bow stuffs.

Very interesting to see those NAIAD active stabilizers in actual operation in seas large enough to reveal them . Of course that means that at the point we can see then they aren't helping a heck of a lot. Big seas!

NAIADs aren't all that effective in head seas anyway. And if you note the angle of the fin doesn't seem to change from photo to photo. So my guess is they were lock or pinned at center position. I think I read somewhere in the blog that the seatrial pictured may have been done without the NAIADs operational.

Of course the odd angle they have the fins at on the hull may indicate they are trying to get them to work at helping with pitching. Or perhaps they are active at anchor.
